摘要
对中药薏苡(Coix lachryma-jobi L)进行了染色体计数和核型分析,结果表明:薏苡的染色体数目为Zn=20,10对同源染色体均为中部着丝点染色体,染色体的绝对长度在2.26～10.5μm之间,相对长度在7.19%～13.02%之间。薏苡的核型公式为:K(2h)=20=20m。本实验为中药薏苡的药材鉴别,在染色体水平上,提供了更准确的细胞学依据,并为抗癌中药的研究提供资料。
The counts of the chromosome and karyotypeanalysis of coix lachryma-jobi L. (a traditional Chi-nese medicinal herb) are represented in this pa-per. The results show that the number of the chro-mosome of coix lachryma-jobi L. is 2n=20. All ofthe homologous chromosomes have median kine-tochrores. The absolute length of the chromo-somes tanges from 2. 26～10. 5μm. The relativelength is 7. 19～13. 02%. The karyotype formulais K (2n)=20=20m. These results provide morecritical cytological criteria for identification of Coixlachryma--jobi L. on the chromosomal level. Inaddition, It can be provided the data for studyingof the fraditional Chinese medicinal herbs againstcancer.
